Just a few days ago I read a stunning statistic.
Only 7% of people who receive CPR after cardiac arrest are alive one year later.
I had no idea.
IIRC, that may be the number for “alive and unimpaired”; i.e., who haven’t suffered brain damage while their hearts were stopped, but yes, the number of people who are brought back by CPR and/or a full code is a lot less than you’d believe from TV and the movies.
Don’t get me wrong - 7% beats 0%, which is what you’d have with no CPR. Still, it’s no magic wand.
